ABB AO2000 LS25 Laser analyzer

ABB AO2000 LS25 Laser analyzer

Specific Parameters​

• Power Supply Parameters: The power supply unit converts 100 – 240 volts of alternating current into 24 volts of direct current. If there is 24 volts of direct current, it can directly supply power to the transmitter device.​
• Signal Input: The 4 – 20 mA input signal from the external gas temperature/pressure sensor can be connected to the screw terminals in the power box or directly to the cable connector on the transmitter unit.​
• Communication Interfaces: The RS – 232 port is used for direct serial communication with a PC. The optional Ethernet board provides TCP/IP communication via a local area network (LAN) and can replace serial communication. All cable connectors are of the Phoenix VARIOSUB type and are waterproof.​
• Measurement Principle: Based on infrared single – line absorption spectroscopy, each gas has a unique absorption line at a specific wavelength. By measuring the change in light intensity after the laser wavelength is absorbed by the target gas molecules in the optical path, combined with wavelength modulation technology, the concentration of the absorbed gas is measured using the second – harmonic of the detector signal.​
• Protection Level: The environmental protection levels of both the transmitter and the receiver are IP66.​
• Pressure – Bearing Capacity: The standard optical windows can withstand a maximum pressure of 5 bar (absolute pressure).​

Product Performance​

• High – Precision Measurement: Using advanced laser technology and a unique measurement principle, it can accurately measure the concentration of a variety of gases with high measurement accuracy, providing reliable data for industrial production, environmental monitoring, etc.​
• Strong Stability: The instrument’s units are made of high – quality materials and have an excellent design. For example, the aluminum box protection of the transmitter and the receiver and the stable power conversion device enable it to operate stably in different environments and reduce measurement errors.​
• Good Anti – Interference Ability: Through specific wavelength selection and modulation technology, it can effectively avoid cross – interference from other gases, ensuring that the measurement results accurately reflect the concentration of the target gas.​
• Convenient Operation and Maintenance: The optical alignment is easy to operate, the purging device is simple to maintain, and it has a variety of communication interfaces, which is convenient for data transmission and remote monitoring, reducing maintenance costs and difficulties.​
